Huitt-Zollars provided design services for a booster pump station, two 1.5 MG ground storage tanks, a 1.5 MG elevated storage tank, and a master meter/rate of flow controller connection to the El Paso Water Utilities system to serve the Fort Bliss area formerly called East Biggs. The East Biggs Development Area is a 2,500-acre master planned military facility.
City of Mesquite experienced some pipeline collapse and pipeline/manhole deterioration along portion of the North Mesquite Creek trunk mains due to hydrogen sulfide. The City had made some Cure-In-Place-Pipe (CIPP) emergency repairs through the BuyBoard program but it was not project specific or cost effective.
Huitt-Zollars prepared construction documents for the rehabilitation of sanitary sewers within the Point Aquarius Municipal Utility District. In order to begin the rehabilitation program, Huitt-Zollars televised the sanitary sewer system, reviewed the videos, designed construction documents, and oversaw the construction of approximately 8,350 linear feet of eight-inch and 12-inch sewer pipe.
Huitt-Zollars, as a consultant, provided civil engineering, architectural design, interior design, and landscape architecture for the $69 million plant, one of the City of Sugar Land’s largest Capital Improvement Projects ever. Huitt-Zollars provided design services for the entire 40-plus-acre site, pump station buildings, maintenance building, sludge dewatering building, chemical building, main electrical distribution building, and membrane/administration building.
Huitt-Zollars designed 4,500 linear feet of 72-inch waterline, along 12th Street, as part of the Accelerated Surface Water Transmission Program. The project limits extended west of IH 610 East to Seamist Drive. Scope of the work included survey, geotechnical and environmental investigations, preliminary and final design, the preparation of storm water pollution prevention plan, traffic control plans and construction phase engineering services. Huitt-Zollars designed three separate tunnels for the project: beneath Highway 610, the Union Pacific Railroad and a private railroad spur.
Huitt-Zollars designed more than 20,000 linear feet of 48-inch water main. The project was located in the middle of a six-lane, divided thoroughfare. Primary concerns involved minimizing the project impact to existing utilities, traffic, adjacent residents and businesses, while protecting all large trees. The scope of work included boring under a railroad, two creeks, and one congested intersection. A plan was prepared to deal with contaminated soils discovered during project design.
The project included facility improvements to four sanitary sewer lift stations including the installation of natural gas generators at each site ranging from 60KW to 160KW, control buildings, odor control devices, paving, lighting, and fencing upgrades.
Huitt-Zollars provided construction plans, specifications and related right-of-way documents for an 8,100-linear-feet section of 48-inch water main; the project was located along a four-lane undivided collector street. Significant project considerations and extensive coordination involved Dallas Water Utilities, TXU, neighborhood representatives, an underground booster pump station, and city council staff.
As the Design Engineer and Construction Manager, Huitt-Zollars prepared a Preliminary Study Report to assess the condition of approximately 16,000 linear feet of the Grouse Street Force Main. The study includes population projections, hydraulic analysis and evaluation of route alternatives, and cost-effective methods to rehabilitate/replace the main. The new force main line is a 30-inch PVC sewer pipe (165, DR 25).
Huitt-Zollars prepared the plans and specifications for the Point Aquarius Municipal Utility District's upgrade of the wastewater treatment plant. Upgrades include a new chlorine contact chamber to replace the original one that was badly deteriorated. Huitt-Zollars also designed a two pump gray water system to reuse water from the chlorine contact chamber for facility washdown purposes. The project was completed on time and within budget.
